| 7 | # SYNOPSIS | |
| 8 | # | |
| 9 | # AX_PROG_JAVA | |
| 10 | # | |
| 11 | # DESCRIPTION | |
| 12 | # | |
| 13 | # Here is a summary of the main macros: | |
| 14 | # | |
| 15 | # AX_PROG_JAVAC: finds a Java compiler. | |
| 16 | # | |
| 17 | # AX_PROG_JAVA: finds a Java virtual machine. | |
| 18 | # | |
| 19 | # AX_CHECK_CLASS: finds if we have the given class (beware of CLASSPATH!). | |
| 20 | # | |
| 21 | # AX_CHECK_RQRD_CLASS: finds if we have the given class and stops | |
| 22 | # otherwise. | |
| 23 | # | |
| 24 | # AX_TRY_COMPILE_JAVA: attempt to compile user given source. | |
| 25 | # | |
| 26 | # AX_TRY_RUN_JAVA: attempt to compile and run user given source. | |
| 27 | # | |
| 28 | # AX_JAVA_OPTIONS: adds Java configure options. | |
| 29 | # | |
| 30 | # AX_PROG_JAVA tests an existing Java virtual machine. It uses the | |
| 31 | # environment variable JAVA then tests in sequence various common Java | |
| 32 | # virtual machines. For political reasons, it starts with the free ones. | |
| 33 | # You *must* call [AX_PROG_JAVAC] before. | |
| 34 | # | |
| 35 | # If you want to force a specific VM: | |
| 36 | # | |
| 37 | # - at the configure.in level, set JAVA=yourvm before calling AX_PROG_JAVA | |
| 38 | # | |
| 39 | # (but after AC_INIT) | |
| 40 | # | |
| 41 | # - at the configure level, setenv JAVA | |
| 42 | # | |
| 43 | # You can use the JAVA variable in your Makefile.in, with @JAVA@. | |
| 44 | # | |
| 45 | # *Warning*: its success or failure can depend on a proper setting of the | |
| 46 | # CLASSPATH env. variable. | |
| 47 | # | |
| 48 | # TODO: allow to exclude virtual machines (rationale: most Java programs | |
| 49 | # cannot run with some VM like kaffe). | |
| 50 | # | |
| 51 | # Note: This is part of the set of autoconf M4 macros for Java programs. | |
| 52 | # It is VERY IMPORTANT that you download the whole set, some macros depend | |
| 53 | # on other. Unfortunately, the autoconf archive does not support the | |
| 54 | # concept of set of macros, so I had to break it for submission. | |
| 55 | # | |

| 59 | # This is a sample configure.in Process this file with autoconf to produce | |
| 60 | # a configure script. | |
